Abstract

The aim of this study is to consider the adsorption phenomena at the electrode/solution interface in systems containing complexes of cucurbit[7]uril (CB7) with organic compounds: adamantanol‑1, ferrocene and organic dye 3,3′‑diethylthiocarbocyanine iodide. These guests form exclusively stable inclusive complexes with CB7. Experimental dependences of differential capacitance C as a function of potential were used in calculating the adsorption parameters characterizing the most important properties of adsorption layers formed by compounds under study at the electrode/solution interface. For all the systems studied here, as for those studied earlier, adsorption parameters for negative and positive charges of the electrode surface differ. Obviously this points to deep changes in the properties of adsorption layers depending on the electrode potential.
